Finite element modelling to determine shell stresses around lifting attachments

We routinely use finite element modelling to determine shell stresses around lifting attachments where the shell geometry or lifting attachment details fall outside the design provisions of the pressure vessel codes. In this example a 125 tonne pressure vessel is being lifted by trunnions which are welded to the shell via compensation plates close to the torispherical end.

Sample analysis

In-house computer programs for the analysis of heavy lifting and transportation operations

We have developed a specialist range of in-house programs for the detailed analysis of heavy lifting and transportation operations. These include programs for the analysis of transportation by ship and trailer, the rearing of petrochemical vessels and the dynamic behaviour of moving loads. These programs are used to check stability and provide design forces for loaded structural elements.

Construction standard detail drawings are produced on AutoCAD and StruCad.
